The loan comprises about 42 percent of the $180 million purchase price, which comes out to $883 per square foot.

A representative for Vanbarton confirmed the firm closed on the property, but declined to comment on the loan.

The building is located at the corner of East 41st Street, just a block from Grand Central Station.

Vanbarton, led by Richard Coles and Gary Tischler, and an unidentified pension fund partner are planning to renovate the lobby and elevators, the firm said.

The building is 66 percent occupied, with floor plates ranging from 3,000 to 11,000 square feet, according to Vanbarton. CBRE’s Paul Amrich is marketing the building’s vacant space for lease.

In 2007, the Marciano brothers had bought the leasehold in partnership with Metropolitan Real Estate Advisors from SL Green Realty. They added the land in 2012. Herald Square serves as the property manager. Corporate services company Hogg Robinson and financial services firm Burford Capital are among the tenants.
